NSW Peak Demand Reduction Scheme
See your NSW battery rebate in 30 seconds
Most NSW homeowners have no idea their battery earns a state rebate on top of the federal discount. That's real money left on the table. This calculator runs the exact PDRS formula and shows what your battery is worth in PRCs, before you spend a cent.
Enter your battery size. We'll show you the Peak Reduction Certificates it earns and what they're worth in cash off your install. No email needed for the estimate.
Your setup
Counted capacity is capped at 5 kWh per dwelling.
Counted capacity is capped at 4 times your inverter output.
Leave blank and we'll use 90% of nameplate, the standard PDRS figure. Override it if your spec sheet lists a different usable capacity.
The traded price moves with the market. Edit it to the current rate for a sharper estimate.

▶ How this number is built
DISCLAIMER: Estimate only. PRC value changes with the market and after your Accredited Certificate Provider's admin fees, so the final figure will differ. Home and small business activities start 1 July 2026. Apartment, business and commercial activities start 1 September 2026. Batteries earn NSW Peak Reduction Certificates. Solar panels earn federal Small-scale Technology Certificates. A NSW project can claim both. This tool does not constitute financial advice.
NSW Peak Demand Reduction Scheme FAQ
How the rebate is worked out
The NSW scheme deems the value upfront as Peak Reduction Certificates.
- Usable capacity: 90% of your battery's nameplate size, unless your spec sheet says otherwise.
- Shifting capacity: Usable capacity times the activity rate gives the peak demand you can shift, in kW.
- Capacity removed: That times a 6-hour peak window, times the battery's deemed lifetime, gives the total capacity taken off the grid.
- Certificates: Your network loss factor is applied, then multiplied by 10 and rounded down. That's your PRCs. PRCs times the PRC price is your rebate.
What makes a battery eligible
Every project has to clear these gates before certificates can be created.
Battery on the Clean Energy Council approved products list. Every Sumray ESS unit qualifies. Installed by an accredited installer, with network and planning approvals in place.
Installed inside the activity's date window. Home and small business start 1 July 2026. Apartment, business and commercial start 1 September 2026.
Business and commercial batteries are claimable once per site and need new solar of at least a quarter of the battery's usable capacity.
Why timing matters
The higher rebate rate only applies if your battery goes in within 90 days of new solar. Miss that window and the rate drops, for the same hardware. PRC prices also move with the market, so the number you see today is not locked in. The sooner you install, the sooner the value is claimed off your invoice.
